Owning Palette: Nonlinear Systems VIs

Installed With: FPGA Module

Detects state changes of Boolean input points. You can choose from three detectors: either, false-true, or true-false.

	initialize, when TRUE, stores input and sets crossing to FALSE. The VI initializes automatically when you first call it in a VI.
	input is the Boolean data the VI compares with the previous value of input.
	direction is the kind of Boolean crossing. You can choose one of the following settings: either, false-true, or true-false.
	crossing is TRUE if a Boolean crossing occurred.
